On the window frame, measure from the middle of the frame on the left to the middle of the frame on the right, this results in the order width. Please make sure to check whether the fabric can run past the window handle. In order to cover the pane completely, however, the width should be at least 4cm wider than the pane. In front of the window niche, first, measure the niche width. To cover the entire window niche, order a roller blind that is approximately 20cm wider. The height can be measured from the ceiling to the window sill or, if desired, to a lower point. How to measure correctly, please use only fixed measuring tapes. The width measurement for roller blinds is the so-called pin measurement. The pin size is wider than the fabric size, so the fabric will be approx. The 4cm is narrower than the ordered roller blind width. The maximum depth of the window frame must not exceed 2cm and not be less than 1cm without a seal to the total width of the roller blind. The fabric width is approx 4cm narrower than the indicated total width. If the roller blind shutters, hooks when pulling down, please check whether you are pointing the mouth, the open part of the head of the chain hoist outwards correctly that the chain blocks. If so, please turn the head of the chain hoist until the open part is covered, then the problem is solved.
